Part 2/10:
The Nasca civilization in Southern Peru is often remembered for its massive geoglyphs, mysterious drawings visible only from the sky. But the Nasca also crafted an extraordinary feat of engineering: the Cantio aqueducts, constructed between 200 and 900 AD in one of the driest places on Earth. These subterranean channels siphoned off precious water from underground sources, utilizing gravity to transport water to parched fields.
The aqueducts employed spiral-shaped openings known as "peos" that served to ventilate the system and facilitate maintenance. Remarkably, this ancient water management system continues to operate today, supporting local communities as they irrigate crops and access clean water.
